Abstract

Microstructures, properties and technical parameters of the welds carried out by the electron beam welding (EBW) process have been investigated in the present paper. Electron beam welding (EBW) is a fusion joining process particularly suitable for the welding titanium. Electron Beam welding is a natural choice for use with materials susceptible to oxidation such as titanium because the EB welding process must occur in a vacuum. During research a two-pass welding technique was developed. In paper there was investigated the electron beam welded joint made of titanium alloy. The weld qualification was carried out by mechanical properties and microstructure evaluations were carried out to ensure the joint integrity. Microhardness measurements of the weld where taken using Matsuzawa Vickers MX 100 type with applied load 100 g (0.98 N). Light microscopy Nikon Eclipse MA200 was used for examination of the microstructure and determination of the size of the specific joint zones.
